With a breakdown voltage range starting at 44.7 V minimum, the device stays transparent below the rail voltage and only conducts when the transient exceeds that threshold. This is the standard selection logic for a DC bus or signal line that must ride through surges without interrupting normal operation. ## DO-214AB SMC — board-fit and thermal path The large tab area on the SMC body conducts heat from the die to the PCB copper during a pulse — the 1500 W rating assumes a standard footprint with adequate pad area for thermal sinking.","metaTitle":"Littelfuse 1.5SMC47A TVS Diode, 1500W, 40.2V Standoff","metaDescription":"Littelfuse 1.5SMC47A Zener TVS diode, 1500W peak pulse power, 40.2V reverse standoff, 64.8V clamp at 23.5A.
